So... I have added an F31 335d Shadow Edition to the garage, daily driver for wifey. Early impressions are that its a belter of a car and should hold us in good stead for a few years to pile some miles on.

I'm not keen on the rear end though... a twin pea shooter for an exhaust on the left hand side lets it down terribly.

Has anyone converted to the Cobra Sport dual pipe (a la 340i style)? If so, are you happy with it? Any feedback? Or is there another system that some of you may have used?

Got one myself as a daily.. great car.. agree the tailpipe does let it down, quite a few folks have done the mod from a 340, which has the dual pipes eitherside. Checkout the f30 section on bimmerpost..
